Description

  The present invention relates to a powdery composition and a hair dyeing or hair bleaching kit using the same.

  In order to suppress the reaction during storage of the hair dye composition or the hair bleaching composition and to increase the dyeing power and decoloring power, the present inventors have supported the powdery composition by supporting alkanolamine on the powdery carrier. It was examined that it was used as a mixture with a hydrogen peroxide solution. However, it was found that such a powdery composition volatilizes alkanolamine during storage and reacts with other compounding components such as ammonium halide to generate ammonia. The volatilization of the alkanolamine causes not only the problem of bad odor due to ammonia, but also the problem of a decrease in the dyeing power as a hair dye and the decoloring power as a hair bleaching agent.

  As a result of suppressing the volatilization of alkanolamine due to storage by setting a compound having a solubility parameter close to that of alkanolamine on a powder carrier together with alkanolamine, the present inventors have reduced alkanolamine and ammonium halide. It has been found that the generation of ammonia due to the reaction with other compounding components and the like, and the decrease in dyeing power and decoloring power can be suppressed.

Reference Experiment 20 g of powdered ammonium chloride was placed in a sealed bottle (Hoshi Glass Co., Ltd., 0.5 L) and stored at 50 ° C. for 1 month with the lid closed. The container lid after storage was opened and checked for the presence of ammonia odor, but no ammonia odor was confirmed.
Similarly, 20 g of powdered ammonium chloride is put into a 0.5 L sealing bottle (Hoshi Glass Co., Ltd.), and further 20 g of 2-amino-2-methyl-1-propanol is put into a PET screw vial (manufactured by Nikko Hansen Corporation, 30 mL) was placed in a sealed bottle with the lid open, and stored at 50 ° C. for 1 month without ammonium chloride and 2-amino-2-methyl-1-propanol in direct contact. When the container was opened after storage and the presence or absence of ammonia odor was confirmed, it was confirmed that ammonia odor was present.
From this experiment, it is suggested that ammonia is generated by the vaporization of 2-amino-2-methyl-1-propanol reacting with ammonium chloride.
